set_display_switch_callback(3alleg4) Allegro manual set_display_switch_callback(3alleg4)NAME
set_display_switch_callback - Installs a switching notification callback. Allegro game programming library.
int set_display_switch_callback(int dir, void (*cb)());
Installs a notification callback for the switching mode that was previously selected by calling set_display_switch_mode(). The direction
parameter can either be SWITCH_IN or SWITCH_OUT, depending whether you want to be notified about switches away from your program or back to
your program. You can sometimes install callbacks for both directions at the same time, but not every platform supports this. You can
install several switch callbacks, but no more than eight on any platform.
Returns zero on success, decreasing the number of empty callback slots by one. Returns -1 if the request is impossible for the current
platform or you have reached the maximum number of allowed callbacks.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Here are some examples of what I've tried:
